One of Super Geeks!

Every Perl Mongers want to write a code like him.

We can’t be Tatsuhiko.

Because we lose the “PURPLE THING” .

PURPLE THING

What’s This?? I don’t know what is this purple thing. But we need this to be like Tatsuhiko! So, I made a “miyagawanize” script. Like “geek face generator” by Yappo-san.

I don’t know what is this purple thing.

But we need this to be like Tatsuhiko!

So, I made a “miyagawanize” script.

Like “geek face generator” by Yappo-san.

How to make “miyagawanize” Make a image of purple thing. Install OpenCV library. Install “Imager” and “Image::ObjectDetect” modules from CPAN. Write a short script. Run a script.

Make a image of purple thing.

Install OpenCV library.

Install “Imager” and “Image::ObjectDetect” modules from CPAN.

Write a short script.

Run a script.

#!/usr/bin/perl use strict; use warnings; use Imager; use Image::ObjectDetect;

my $file = shift or die "image file path is required!"; my $image = Imager->new->read( file => $file ); my $cascade = './haarcascade_frontalface_alt2.xml'; my $detector = Image::ObjectDetect->new($cascade); my @faces = $detector->detect($file); my $purple_source = Imager->new->read(file => './purple.png'); my $aspect = 1.5;

for my $face (@faces) { my $purple = $purple_source->scale( xpixels => $face->{width} / $aspect, ypixels => $face->{height} / $aspect, ); $image->rubthrough( tx => $face->{width} / $aspect / 2 + $face->{x}, ty => $face->{height} / $aspect + $face->{y}, src => $purple, ); } $image->write( file => './output.jpg' );

DEMO

Let’s “miyagawanize”, And write a great code! Thanks to Tatsuhiko Miyagawa!!
